Trifloxystrobin microcapsule suspension and preparation method thereof

Abstract

The invention discloses trifloxystrobin microcapsule suspension and a preparation method thereof. The trifloxystrobin microcapsule suspension comprises, in weight percentage, 1%-10% of trifloxystrobin, 3%-20% of capsule core solvent, 5%-30% of capsule shell material, 2%-10% of emulsifier, 1%-5% of dispersant, 0.1%-5% of antifreezing agent, 0.1%-10% of pH regulator, and the balance of deionized water. The invention further discloses the preparation method of the trifloxystrobin microcapsule suspension. The trifloxystrobin microcapsule suspension is high in physiochemical stability and high in emulsification dispersion, and is efficient, wide-spectrum, low-toxic and pollution-free miticide. The problem that combination of the trifloxystrobin with soil affects drug effect is solved. In addition, consumption is lowered under slow control, so that drug validity is prolonged, control effect is enhanced, the pesticide is less apt to be damaged by atmosphere, sunlight and rainwater and less easy to run off, underwater pollution is controlled effectively, and change of ecological environment is prevented.

Description

Technical field [0001] The invention belongs to the field of pesticides, and specifically relates to a trifloxystrobin microcapsule suspension and a preparation method thereof. Background technique [0002] Chemical control is an important means for humans to prevent agricultural and forestry pests and diseases. Chemical pesticides play a very important role in ensuring increased agricultural production and income. However, the use of pesticides, while ensuring safe food production, also brings about a series of environmental problems such as residues and pollution. and social issues. This is only due to the chemical pesticides themselves, and to a large extent due to unreasonable processing and application methods of pesticide formulations. According to reports, the utilization rate of conventional pesticides is only 20% to 30%, and the loss rate through various channels is as high as 50% to 60%. This is not only an economic waste, but also causes a wide range of environme...

AI Technical Summary

Problems solved by technology

There are some obvious deficiencies in the existing dosage forms, such as the presence of a large amount of organic solvents in the emulsifiable concentrate preparations, which is a potential pressure on the environment; wettable powders are prone to dust pollution during production, transportation, and use, and the processing process consumes energy. Large particle size affects the absorption and conduction of pharmaceuticals; the production process of water-dispersible granules and dry suspensions is prone to dust pollution, energy consumption, and low production efficiency; the production process of suspensions consumes energy and has low efficiency. Conducive to the absorption and conduction of the medicine, under the action of natural gravity, the medicine liquid is easy to settle to the bottom

Trifloxystrobin microcapsules still need to use a certain amount of aromatic hydrocarbon organic solvents, and no suitable synergist is added, the control effect is poor, the drug effect lasts for a short time, the application concentration of trifloxystrobin is high, and the control cost is high
